High-temperature cooling water waste heat recovery system of fuel gas internal combustion generator

The utility model relates to the technical field of waste heat utilization, in particular to a fuel gas internal combustion generator high-temperature cooling water waste heat recovery system which comprises an ORC power generation system and a cooling tower. The ORC power generation system comprises a superheater, an evaporator and an expansion machine which are sequentially connected, the superheater is connected with a cooling water outlet of the fuel gas internal combustion generator through a first pipeline, the evaporator is connected with a cooling water inlet of the fuel gas internal combustion generator through a second pipeline, and cooling water flows out of an outlet of the fuel gas internal combustion generator to enter the superheater. Entering the evaporator from the superheater, and entering the fuel gas internal combustion generator from the evaporator; an organic working medium in the ORC power generation system exchanges heat with cooling water of the fuel gas internal combustion generator
